PI audio group is a different kind of company.






The BUSS-Line Design Criteria


Power conditioning can be a mixed bag when it comes to high performance audio and video.  Almost all of the available power conditioners are comprised of three components in the noise reduction end of the equation.  These are: inductive components – either chokes or transformers; high frequency capacitive filters; and MOVs (metal oxide varistors).  The purpose of the inductive components is to either provide transformer isolation, balanced power or to introduce a 6dB/octave high frequency roll-off.  The capacitive filters increase the roll-off slope above their corner frequency.  The MOVs are used for local surge protection.


The problem with these commonly used components is that they are only partially effective in most cases.  The inductors are either too small to be effective at audio frequencies or too large and cause current limiting in the circuit.  Balanced power is a good thing, but the transformers used for this are generally limited in instantaneous power delivery.  The capacitive filters are too small to be effective below ~ 100KHz in most instances.  The MOVs will begin to produce noise after a while and are “used up” over a period of time and need to be replaced to prevent them from producing noise.


The BUSS-Line from PI audio group, LLC was developed as a result of many years of research in noise reduction for use in the recording industry.  The design targets were easy to set, but hard to achieve.  The BUSS had to be non-limiting in current, effective well down into the lower midrange of audio frequencies and be absolutely reliable.  This meant the elimination of MOVs in the circuit.  The UberBUSS and RevB MajikBUSS are not surge protectors.  They are leading edge power filters that produce dead silent backgrounds at audio frequencies.  In addition, they incorporate a Power Factor Correction section that will increase instantaneous current delivery to equipment attached to them.  Dynamic contrasts are immediate and transparent.  This has to be experienced to be appreciated.  For those that want surge protection there is the BUSS-Stop.  It is a combination of surge limiting components arranged in a manner to be as quiet as possible during operation.


The Buss-Line is not only a great choice for audio.  It is a great addition to a video system.  Color saturation is deeper, blacks are blacker and images are clearer when the power is scrubbed clean by a BUSS.
